单词 quadrillion
释义

quadrillionn.adj.

Brit. /kwɒˈdrɪljən/, /kwəˈdrɪljən/, U.S. /kwɑˈdrɪljən/
Forms: 1600s quatrilion, 1600s– quadrillion.
Origin: A borrowing from French. Etymons: French quadrillion, quatrillion.
Etymology: < French quadrillion (1484 in Middle French in sense ‘a thousand times a thousand trillions’; also quatrillion, although this is apparently first attested later than the corresponding form in English: 1765) < quadri- quadri- comb. form + -illion (in million million n.).With the form quatrilion compare discussion at quadri- comb. form.
A. n.
Originally: the cardinal number equal to the fourth power of a million, represented by 1 followed by twenty-four zeros (1024) (now chiefly British). Later also (originally U.S.): the cardinal number equal to the fifth power of a thousand, or 1 followed by fifteen zeros (1015). Also hyperbolically: an unspecified but very large number or amount.The displacement of the original sense by the later one is similar to that described for billion (see billion n.).
